Specification of Letters Patent.

Patented Aug. 22, 1916.

Application filed October 9, 1915. Serial No. 55,120.

To all whom it may concern: I

Be it known that I, LEON WVEISS, a citizen of the United States, and a resident of New York city, in the county of Bronx and State of New York, have invented certain new and useful Improvements in Collapsible (ores for Molding Dolls Heads, of which the following is a specification.

This invention relates to collapsible cores for molding dolls heads or similar hollow molded articles.

Among the objects of the invention are to provide a core of this character which is of minimum weight, so that it maybe more conveniently handled; to make the core very readily attachable and detachable so as to facilitate the work in molding the articles; and to provide interlocking means which is siniplefetfective and easily manipulated.

The various further objects and advantages will more fully appear from the following detailed description and the features of novelty will be particularly pointed out in the claims.

In the drawing illustrating the invention, Figure 1 is an elevation of the improved core assembled. Fig. 2 is a top plan view, aiid Fig. 3 is a sectional plan view, taken along line 33of Fig. 1. Fig. 4 is a section similar to Fig. 3, the section being taken along line 41 of Fig. 1. Fig. 5 is a frag: mental longitudinal sectional view illustrating the locking means for the lower end of the core sections. Fig. 6 is a plan view of the central post and handle detached from the core sections. Fig. 7 is an enlarged fragmental elevational view of the upper end of one of the core sections, showing the dovetail and the strengthening rib. Fig. 8 is an enlarged fragmental perspective view of the central post tov which the core sections are attached.

Referring in detail to the drawing, the improved core comprises a central hollow, preferably angular, post member 10, about which are attached a number of core sections 11, 12, 13, etc., which make up the form of the core. These core sections are cast with a thin body portion 14 formed to the required configuration and with an internal strengthening rib 15 which gives the required stiffness without increasing the weight to any appreciable extent. The four major sections 11, 18, etc., are attached to the central post by dovetail connections 16, mating in correspondingly formed recesses 17 in a block 18, secured to the top of the post. 10. The minor core sections 12 have also dovetail projections 19 which engage corresponding recesses formed in the adjacent ma or core sections, and are held securely thereto by abutting the post 10, as clearly appears from Fig. 2.

To assemble the core, the major sections are slid into the proper position on the post with the dovetail 16 engaging in the recesses, and then the minor sections are slid over the major sections in position between the latter and the central post, and then the bottoms of the core sections are securely locked and positioned as follows: Within the post 10 is a rod 20 to secure the upper end to the plate 18. At the lower end of this rod is mounted a handle 21 and above the handle is secured a collar 22 surmounted by a portion 23 which may be integral or separate therefrom having the wedge shaped positioning lugs These lugs are engaged in correspondingly shaped recesses 25 formed in the bottom of the major mold sections 11, 13, etc. Projecting from the collar 23 and through post 10, are the pins 26 having the tapered ends 27 engaging in correspondingly shaped recesses formed in the interior surface of the ends of the core sections. Thus, when the core sections are positioned as above described, the bottom portions will engage with the pins and when these portions are held to the central post, the entire structure is rigidly heldtogether.

I provide simple and easily operable means for holding the bottom of the core sections to the central post. This means consists of a sleeve 28 slidable on a guide 29 formed above the handle 21. Then the sleeve is raised to the position illustrated in Figs. 1 and 5, the bottoms of the core sections are embraced Withinthe interior of the sleeve and securely held against the post 10 and the pins 26. To prevent the core from turning in the mold, the usual projection 30 is provided upon one of the core sections.

It will be clear, therefore, that I have provided a core for molding dolls heads and similar articles which is of light construction and easily operable, to hold the core sections together or to collapse the same when the core is to be removed from the mold. All of these features are of great importance as the core has to be handled a great many times by the operator and the cost of the finished molded product is dependent to a large extent on the speed and facility with which the work may be done.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A core for molding dolls heads and similar articles comprising a central post, a plurality of core sections attached at the upper ends thereof, centering and interlocking means on the post engaging with the bottom of the core sections, and means for holding the core sections against said centering and interlocking means.

'2. A core for.nmhling dolls heads and similar articles comprising a central post,

a plurality of core sections attached at the upper ends thereof, a plurality of pins projecting from the central post, there being recesses formed at the bottoms of the core sections to engage said pins, and means movable on the post for-holding the bottoms of the core sections in engagement with the pins.

3. A core for molding dolls heads and.

similar articles comprising a central post, a plurality of core sections attached at the upper ends thereof, a plurality of pins and centering wedges pro ecting from the central post, there being recesses formed at the bottoms of the core sections to'engage said pins, and means movable on the post for holding the bottoms of the core sections in engagement with the pins.

4. A core for molding dolls heads comprising a hollow central post, a block closing the top of the post formed with recesses, a plurality of core sections having dovetail portions at the upper ends thereof engaging the recesses, and means for securing the bottom of the sections against the post.

5. A core for molding dolls heads comprising a central post, a plu 'ality of major core sections having interlocking engagement with the top of the post, a plurality of minor core sections interlocking with the major core sections, and means for securing the bottoms of the core sections to the post.

6. A core for molding dolls heads comprising a post formed with recesses in the top thereof, a plurality of major core sections having dovetails registering with said recesses, a plurality of minor core sections having dovetails inter-engaging in recesses formed in the major core sections and held in place between the major core sections and the central post, and means for securing the lower core sections to the post.

7. A core for molding dolls heads or similar articles comprising a centralhollow post, and hollow core sections interlocking therewith and a longitudinal strengthening rib for each of the hollow core sections.

8. A core for molding dolls heads comprising a hollow angular central post member a block having recesses therein dis posed at the top of the post, a rod secured to the block and passing through the post,

a handle secured to the opposite end of the rod, core sections engaging in the recesses in said bloclgand means for securing the core sections to the central post.

9. A core for molding 'dolls heads comprising an angular central hollow post having recesses disposed at one end thereof, a rod passing through the post, aycollar disposed on the rod at the lower end of the post, pins projecting from the collar through the post; core sections engaging the recesses at the top of the post and with the pins at the bottom of the post, and means for holding the core sections in engagement with the pins.
